+2007-07-26 Major rewrite of mathtext.py, using the TeX box layout model.
+
+ There is one (known) backward incompatible change. The
+ font commands (\cal, \rm, \it, \tt) now behave as TeX does:
+ they are in effect until the next font change command or
+ the end of the grouping. Therefore uses of $\cal{R}$
+ should be changed to ${\cal R}$. Alternatively, you may
+ use the new LaTeX-style font commands (\mathcal, \mathrm,
+ \mathit, \mathtt) which do affect the following group,
+ eg. $\mathcal{R}$.
+
+ Other new features include:
+
+ - Math may be interspersed with non-math text. Any text
+ with an even number of $'s (non-escaped) will be sent to
+ the mathtext parser for layout.
+
+ - Sub/superscripts are less likely to accidentally overlap.
+
+ - Support for sub/superscripts in either order, eg. $x^i_j$
+ and $x_j^i$ are equivalent.
+
+ - Double sub/superscripts (eg. $x_i_j$) are considered
+ ambiguous and raise an exception. Use braces to disambiguate.
+
+ - $\frac{x}{y}$ can be used for displaying fractions
+
+ - $\left(\frac{x}{y}\right)$ may be used to create
+ parentheses and other delimiters that automatically
+ resize to the height of their contents.
+
+ - Spacing around operators etc. is now generally more like
+ TeX.
+
+ - Added support (and fonts) for boldface (\bf) and
+ sans-serif (\sf) symbols.
+
+ - Log-like function name shortcuts are supported. For
+ example, $\sin(x)$ may be used instead of ${\rm sin}(x)$
+
+ - Limited use of kerning for the easy case (same font)
+
+ Behind the scenes, the pyparsing.py module used for doing
+ the math parsing was updated to the latest stable version
+ (1.4.6). A lot of duplicate code was refactored out of the
+ Font classes.
